Thin film Co[TCNE]2 and VyCo1−y[TCNE]2 magnetic materials

► Solid solution VyCo1−y[TCNE]2 films have been fabricated by chemical vapor deposition. ► Co[TCNE]2 films exhibit paramagnetic behavior with antiferromagnetic coupling. ► VyCo1−y[TCNE]2 films order as ferrimagnets with Tc's exceeding room temperature.
